INSECT-GUARD FOR GASTERS.

Specification of Letters Patent.

Patented June 17, 1919.

Application filed December 17, 1914. Serial No. 877,758.

To all whom it may concern:

Be it known that I, JOHN T. TAIWIN, citizen of the United States, residing at El Dom rado, Arkansas, in the county of Union and State of Arkansas, have invented certain new and useful Improvements in' Insect- Guards for Casters, of which the following is a specification.

This invention relates to improvements in casters generally, especially ant guards therefor.

The invention has for its object, as indicated, primarily to prevent or intercept ants entering a refrigerator, buffet, etc., by way of ascending the legs or supports of the same, as is commonly the experience.

A further object is to carry out the aforesaid ends in a simple, inexpensive and effective manner.

The invention therefore consists of certain detailed structural features as combined with the furniture caster, substantially as hereinafter more fully disclosed and pointed out in the appended claim.

In the accompanying drawing is illustrated the preferred embodiment of my invention, wherein it will be understood that various changes and modifications may be made as to the detailed construction and arrangements of parts without departing from the scope of the claim, and in which drawing Figure 1 is an elevational vention.

Fig. 2 is a sectional view of the same.

Fig. 3 is a plan view thereof.

In carrying out my invention, I suitably equip a furniture caster designated generally as 1 with what may be termed a guard or baflie 2, said guard or bafile including a top member 3 and a skirt or pendent portion 4 preferably of annular outline. V 2 has its upper portion 3- provided with a central aperture or orifice 5 to receive the spindle 6 of the caster, said spindle having a lateral enlargement or shoulder 7 beneath which takes the upper portion 3 of the guard, around the edges of said aperture or view of my in- The guard orifice, as seen particularly in Fig. 2. The spindle 6 has also applied thereto at a point below the upper portion 3 of the guard, a race member 8 of an inverted concave outline, with its convexity presented to a concavity 9 in said upper portion 3 of the guard. The race member 8, it will be noted, receives within its concavity bearing balls 10, said bearing balls resting upon the upper portion of the caster bracket 11, the caster wheel being designated as 12. The hood Or race member 8 has its lower or marginal edge extended horizontally as at 13 overlying the corresponding surface of the upper end of the caster bracket 11, the conjoint structure of the race member 8 and the upper portion of the caster bracket 11 forming the raceway in its entirety for the bearing balls 10, all of which is apparent from Fig. 2. Also arranged upon the spindle 6 of the caster is a frame like member 14: or which may be tubular to serve as a bushing or socket, in practice, let into the leg of the article of furniture as indicated in Fig. 1, and thus serve to centralize said spindle in position therein and also to enable said spindle to pivot in the furniture leg, as will be appreciated.

It will be observed from the foregoing arrangement of parts that ants or other insects will be bafiied or intercepted in their attempts to enter the article of furniture to which the caster may be applied, particularly by reason of the annular skirt portion of the guard 2, since the ants, even after passing the upper end of the caster bracket, and reaching the under side of the top portion of the guard 2, will be bafiled from making further headway by said annular skirt portion of the guard, as is apparent and the ants or insects thus be prevented from passing thereabove and climbing the furniture leg. The invention, it will be observed, is exceedingly simple, readily manufactured and applied for use at very little expense, either to furniture in use or such when first put upon the market.

I claim:

As an improved article of manufacture,

an insect guard for a furniture caster the received in said concavity and receiving balls to surround the spindle.

In testimony whereof I aflix my signature in presence of two Witnesses.

JOHN T. TARVIN.

same comprising a baiile having a top member and a depending skirt, said top member being dished toward the center and having a central orifice to receive the spindle of the caster, with a Sllll'Olllldillg concavity upon the under side of said top member, and a raceway member having a convex portion Witnesses:
